SKATE.

SPECIFICATION forming part of Letters Patent No. 440,529, dated November 11, 1890.

Application filed May 19, 1890- Serial No. 352,276. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE CHARLES BATEMAN, machinist, a citizen of Canada, residing at Halifax, in the county of Halifax and Province of Nova Scotia, have invented certain new and useful Improvements in Skates; and I do hereby declare that the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof, in which-- Fignre 1 is a perspective view of my improved skate. Fig. 2 is an elevation of the same. Fig. 3 is a top view of the same. Figs. 4, 5, and 6 are details of the device for securing the skate at the toe. Fig. 7 is a view of the fastening device for the heel, as seen from the under side.

The object of my invention is to provide a skate that can be easily and quickly adjusted to any ordinaryboot, the toe and heel fastenings of which act independently of each other, and other improvements, which will be fully set forth hereinafter.

A is the blade of the skate, to the front end of which is secured the top plate B, by means of two forks b 1), formed integrally with the toe-plate, preferably stamped out of sheet metal and bent downward astride the blade A and a standard 0, the lower part of which is forked and secured to the blade by a screw 0. On the upper part of this standard and on opposite sides thereof are projecting teeth D. These teeth project over the toe-plate and hold it firmly on the blade, a circular slot 61 being formed in the toe-plate, having a recess on either side through which the teeth D pass when the skate is being put together.

E E are the toe-clamps, the upright portions e of which are serrated in the usual manner to obtain a grip on the sole of the boot. The horizontal portions are cut away at F, and a recess G out out of this reduced portion, as shown in Fig. 5. The inner edges of these recesses are provided with teeth. g. The projections f left on the ends of the plates serve as a guide in the recessed portion F of the opposite clamp, and also as stops to prevent the clamps being withdrawn. These clamps are covered by a cover-plate H, the edges h of which are turned down and cover the sides of the clamps, forming a slide for the clamps. Pins or buttons I project downward from the diagonally-opposite corners of this coverplate, adapted to pass through and slide in the slots J in the toe-plate 13. These slots J are arcs of a circle of which the screw K is the center. Gross-slots are provided through which the buttons I pass when the skate is being put together. The screw K passes through the co ver-plate H and into the standard C, acting as a pivot for the plate II. A stop L passes up through a hole in the toeplate B, and is attached to a spring thumbplate M, secured to the under side of the toeplate.

It will readily be seen, Fig. 5, that when the spring-stop is depressed the blade A may be turned to one side, so that the teeth of the standard are disengaged from the teeth of the two toe-clamps, which may then be adj usted to any width required. When the required width has been attained, the blade may be then turned back until the cover-plate passes the spring-stop, in which position the teeth of the standard engage the teeth of the clamps. The spring-stop then prevents the blade being turned too far and the teeth disengaged when securing the skate to the boot, but permits a limited contraction of the clamps. It will thus be seen that the blade of the skate is used as a lever, by which the toe-clamps are secured to the boot.

The heel-plate N has two forks a bent down ast'ride the blade and two serrated plates 0 bent upward to secure the back of the heel of the boot. A slot 0 is formed in the front portion of the heel-plate N. Aforked standard P is secured to the blade A by a screw 1) and riveted or screwed to the plate N. Under this plate is a sliding plate Qof the heelclamp, the forward end of which is turned up and passes through the slot 0, and is furnished with a knife-edge 0", turned rearwardly to en gage the heel of the boot. This clamp-plate is provided with two arms R and S, passing one on each side of the standard P. The arm R is provided with a slot 5, adapted to slide on a button T, which holds it in place. The inner edge of this arm is provided with teeth U, adapted to engage teeth V on a lever W,

the toe-plate rigidly secured thereto, theexand recesses communicating with; the slots,

through which the. standard P passesand acts as a fulcrum thereto. The teeth V extend over only a portion of the end of thelever W. The other portion w is left without teeth, so that when the lever is turned back the teeth of the sliding plate and of the lever are disengaged, and the rack-plate or heel-cuttermay be adjusted to any desired size. A- stopl may be attached to the heel-plate, over which the lever may be sprung when the lever is turned back; but in putting on the skate this stop prevents the teeth being disengaged. The lever W is bent over at the outer extremity, forminga hooker-catch m, adapted to engage teeth q, formed on the edge-ofthe; heel-plate. This holds the lever firmly when the skate is on the boot.

In thisskateit willbe seen thatan ordinary-sized toe or hieelj plate can be attac ed 1 ngro hort la er r as in he ates now.- in" use, as the Acme, only the same sized plate can be used with the same-sized blade.
